Abstract:
Thirty-one clinically healthy Labrador retriever dogs of both sexes (18 males and 13 females) were selected for determining Doppler echocardiographic reference values. 2 D and Pulse wave Doppler echocardiography was carried out by using GE Logiq P5 Color Doppler machine. The effect of body weight, age and sex on various doppler echocardiographic parameters were recorded. Twenty four dogs were in body weight range of 20-40 kg and 7 dogs in 40-60 kg range. To study the effect of age on various Doppler echocardiographic measurements, dogs were divided into 4 age groups (1-2, 2-3, 3-5 and >5 years of age). The mitral A wave peak velocity (MA) and ME:MA ratio were significantly (p<0.05) affected by body weight. The pulmonic valve velocity and pulmonic valve pressure were significantly (p<0.05) affected and there was significant negative correlation of pulmonic valve peak velocity (Pulmonary V max) and pulmonary pressure with body weight with r2 values of 0.160 and 0.120 respectively. Mitral valve (MV) deceleration time was significantly (p<0.05) affected by age. The tricuspid valve deceleration time (TVDecT) was significantly (p≤0.01) higher in dogs > 5 years of age. Tricuspid A velocity was significantly (p≤0.01) higher in 2-3 year age group dogs as compared to dogs belonging to age group 3-5 years and > 5 years of age group. The pulmonic valve velocity and pressure were significantly affected by age. The tricuspid valve TE: TA ratio was significantly (p≤0.05) affected by gender and the ratio was significantly (p≤0.05) higher in males as compared to females.
